Pinpoint Test AP: DTC B1892 - Air Bag Tone Warning Indicator Circuit Shorted to Ground or Open

Normal Operation

The Restraints Control Module (RCM) monitors its connection to the Generic Electronic Module (GEM) at C240a-20. This connection is used to signal a chime if the air bag indicator is inoperative and another SRS fault exists. If the RCM detects a short to ground or open on the connection to the GEM, it will store a Diagnostic Trouble Code (DTC) B1892 in memory.

Possible Causes

An air bag tone warning indicator circuit short to ground or open can be caused by:
- a short to ground or open on circuit 1083 (LB/BK).
- a damaged or inoperative GEM.
- an RCM internal concern.
